Output to LCD from QNetworkAccessManager fails

I am trying to make the output of an http get connection stream to an lcd screen (a future http stock ticker), once connected. My code errors with "C:\Qt5\Tools\QtCreator\bin\httpGET\mainwindow.cpp:16: error: no matching function for call to 'QLCDNumber::display() ui->lcdNumber->display()"

First thing I would change is your "connect" method. You should rather use something like setupConnections. If I've read your code correctly, you don't update your lcd anywhere except the constructor. Also in your connect method you are creating an endless loop that will also have as a side effect the re-creation of all connections once you clicked your push button

@SGaist I detected the endless loop.
I am new to Qt and really not sure how to correct the connection. My instinct says to do display(nam) and update it with the object it's self. But this blows obvious errors.
